SALT LAKE CITY — The father and brother of a boy who died of starvation, Gavin Peterson, have pleaded guilty to multiple felony charges relating to his death. Gavin's case shook his community after his death, opening multiple conversations around child safety and the role of the Division of Child and Family Services in protecting children. On Thursday, the guilty pleas entered by Gavin's father and brother were a major development.

In the Second District Court, Shane Peterson, 46, pleaded guilty to first-degree child abuse homicide, three second-degree felony charges of aggravated child abuse, and third-degree felony of endangerment of a child. As part of a plea deal, Shane Peterson’s homicide charge won’t be upgraded to murder, meaning that prosecutors will not be seeking the death penalty, though they did request that his sentence run consecutively. Shane Peterson's plea included an additional charge of aggravated child abuse for the abuse of Mayloni Peterson, his daughter. “I have final say in terms of whether these or not these run concurrent or consecutive and how the sentences are imposed,” Judge Camile L. Neider said. “Otherwise, I will accept the plea negotiation.” The judge also encouraged Shane Peterson to cooperate with a pre-sentence investigation report while acknowledging “it’s a given, the fact that you’re going to go to prison.” Neider said she would rely on the amended information in the charging documents for a factual basis, after Shane Peterson confirmed it was true. Shane Peterson’s sentencing is scheduled for May 6 at 4 p.m.

Tyler Peterson

Gavin's brother, Tyler Peterson, 22, pleaded guilty to first-degree child abuse homicide, two second-degree felony charges of aggravated child abuse, and second-degree felony obstruction of justice. “The state further agrees that the charges may run concurrently when sentencing is officially announced,” Defense Attorney Ryan Bushell said, adding that Tyler Peterson may be required to “cooperate and provide truthful and honest testimony during a trial or a hearing,” presumably during Nichole Scott’s court proceedings — Shane Peterson's girlfriend, who is also accused of abusing Gavin. “As mentioned, the state agrees to allow these pleas of guilty to be … guilty with a mental condition,” Bushell read from the plea agreement. In Tyler’s case, psychological evaluations played a mitigating role. Doctors determined the 22-year-old suffers from autism spectrum disorder, generalized anxiety disorder, persistent depressive disorder, and “other specified personality disorders with avoidant and dependent features.” Due to these mental conditions, the defense argued Tyler Peterson’s sentencing could be postponed until “such time as an evaluation is completed and a recommended treatment plan is provided to the court.” Bushell said the evaluation and treatment plan could be done within the next thirty days but would be facilitated if Tyler Peterson was released from jail to the custody of his biological mother, Melanie Peterson. “We’ve spoken with the mother and (sister,) Mayloni. They both agreed that yes, they would like him to come and stay with them in their home,” a court representative said. The judge agreed to release Tyler to the custody of his mother, Melanie Peterson. However, she issued a pretrial protective order, which prohibits Tyler Peterson from aggressive behavior or domestic violence, and he has to check in with pre-trial services staff at the Weber County jail twice a week. “They want you to come and be with them but it is under some really strict terms and conditions,” Neider said to Tyler Peterson, indicating the release could happen in the next day. The judge is also requiring that Tyler Peterson cooperate with creating a pre-sentencing report, though she does not expect him to be sentenced in the next 45 days. Tyler Peterson is expected back in court on April 24 at 2 p.m. for a review of his treatment assessment.

Gavin's death

On July 9, 2024, Weber County first responders were called to Shane Peterson's West Haven home after a report that his 12-year-old boy, Gavin, was found unresponsive on the bathroom floor. https://ksltv.com/local-news/dcfs-breaks-silence-on-its-involvement-in-child-abuse-case-after-death-of-gavin-peterson/691672/   According to court documents, first responders found Gavin in his father's home and immediately took him to the hospital, where he was pronounced dead. The amended charging information for Shane Peterson said an examination of Gavin's body "showed malnutrition to the point the child’s internal organs had shut down completely. The child’s body was visibly emaciated." In the days following Gavin's death, Shane Peterson and Tyler Peterson were arrested on suspicion they had been abusing him. Shane Peterson's wife, Nichole Scott, 50, was also arrested in the same investigation. Scott had a court hearing on March 7, and an in-person status conference was scheduled for March 27.
